I don't know what those websites say about peak time, but in my experience, you should wait a couple of weeks before you go there. If you want to have a scenic ride though the White Mountain forests, you may want to consider a drive along the Kangamangus Highway. Follow I-93 North to Exit 32 in New Hampshire. At the bottom of exit 32, turn left onto NH 112 East (the Kangamangus Highway). The Kangamangus Highway runs for about 30 - 35 miles along the most beautiful route in New Hampshire.
